SPECIFICATION forming part of Letters Patent No. 670,064, dated March19, 1901.

Application filed October 5, 1900. Serial No. 32,176. (No model.)

in the county of Stearns and State of Minnesota, have invented certainnew and useful Improvements in Band-Cutters for Threshing-lVIachines,ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

My invention relates to band-cutters for threshing-machines, and moreparticularly to manually-fed machines, the object being to provide novelmechanism for the purpose stated which will dispense with the labor ofone or two men.

The invention consists in a sheaf-band-cutting mechanism of peculiarconstruction attached to the feed-board of the device.

It consists also in boxes or receptacles hinged together on the apron orcarrier operating shaft for respectively receiving the bound sheaf andthe sheaf with the band out and in an endless carrier for conveying thebound sheaf from its box or trough forward to the band-cutters andthence to the second box and mechanism for operating said carrier.

The invention finally consists in the novel construction, arrangement,and combination of parts thereof, all as will be hereinafter described,and defined in the claim.

The nature, characteristic features, and scope of the invention will bemore readily understood from the following description, taken inconnection with the accompanying drawings, forming a part hereof, inwhich- Figure l is a top plan view of allied parts of a threshingmachinewith my improvethe upper sheaf-box turned on its hinge-shaft over thelower box.

In said drawings, A is part of the main frame supporting thethreshing-cylinder a and feed-table B, which are of the usualconstruction.

O is a box or trough comprisinga back 0 and two side members 0 Thedimensions of these will naturally vary according to the capacity of themachine; but I have obtained excellent results from a trial apparatuswhen the box was four feet wide, three feet long, and twelve incheshigh. The box O is intended for the reception of the bound sheaf and isabove and in rear of a second box D and is hinged to the latter on ashaft L, the back cl of the box D being inclined or sloped in front ofthe box 0. The bottom d of box D is of irregular shape, being four feetwide on the front and rear edge, sixteen inches long on the sidefarthest from the threshingcylinder to give room to the operator, andtwenty inches long on the side nearest the 'thresher, so that it willrest upon the latter,

its rear part being supported by the brace 61 The box D has its back dinclined and receives the sheaf as it issues from box'O with its bandout.

Above the lateral walls 0 of the box 0 are brace-rods E, which support atransverse plank or platform F, which sustains the beari11g-blocksff fin the first two of which is mounted a shaft G, extending parallel withthe sustaining-plank F. The shaft G carries at its outer end a pulley Hand at its inner end a bevel-gear h, which meshes with a similar gear hon a crank-shaft 7L journaled in bearing f The crank h of said shaftconnects with a rocking bar I, which carries curved or simitar-likeknife-blades i in any desired number, there being five in the presentinstance. An angular brace-rod h is also mounted vertically upon theplank F and carries a journal-pin as a pivot for the connecting-rod h ofthe bar I.

In the bottom of the trough C is a constantly-moving apron or conveyerJ, which runs over rolls K L, journaled at either end of the trough, theroll L carrying belt-pulleys M N. The apron is guided over ways It, asclearly to be seen in Fig. 3. The pulley N receives motion from thethresher in any suitable manner, and a belt 0, connecting pulleys H andM, transmits motion to the bandcutters, the belt being usually crossed,as shown in Fig. 2.

In practice the bound sheaf is thrown into the box 0 with the headstoward the threshing-machine. The apparatus being set in motion, theapron J moves the sheaf forward and the bar I is actuated, causing theknives to move in a downward and rearward reciprocating direction awayfrom the thresher, causing the band of the sheaf to be severed with adraw cut. A bar or fender P is provided horizontally, as shown in Fig.2, to guide the knives and prevent the straw from choking them. Theunbound sheaf is now carried forward upon the apron and falls into thereceiving-hox D, from whence it is removed by the operator and fed tothe thresher.

The dot-ted lines, Fig. 1, illustrate how my attachment can beduplicated, so as to operate t'rom both sides of the machine.

It will be obvious to those skilled in the art to which the inventionappertains that modifications may he made in detail without departingfrom the spirit and scope thereof. Hence I do not limit myself to theprecise construction and arrangement of parts hereinabove described, andillustrated in the accompanying drawings; but,

Having thus described the nature and objects of the invention, what Iclaim is In a band-cutting attachment for threshingmachines an initialbox or receptacle for the bound sheaf, and a second receptacle for theunbound sheaf, the initial box being hinged to the second box andadapted to be folded upward over the second box, said second receptaclehaving its bottom wider toward the threshing-machine cylinder than onits outer side and extended part way over the opening leading into thethreshing-machine substantially as described.

In testimony whereof I atfix my signature in presence of two witnesses.

JOHN SCH U LTE.
